we still did two naps a day. .. but every once in a while it was one nap for the day. the two naps were something like 10:00 and 3:30ish.
as for food.. we would give him a bottle when he woke up.. breaskfast (i honestly cant remember what now!).. but then nap… bottle.. lunch.. another nap.. sometimes snack before it it or after it. .. then dinner and then another bottle before bed.
you can try sweet potato?? maybe very steamed brocolli?? we put the avocado on toast too.. we did egg yolk w/salt on it. sorry, not a lot of help with the food at that age! and it was only 8 mos ago!!
